Simple PWM 555 chip

A simple HHO PWM with 3 potentiometer, adjustable for on and off duration and pulse speed. The mosfet is an irf530 with 100 volts and 14A max specs. You can use any n channel mosfet, depending on your application. By the way im using this for my scooter honda dio. Here is the link of the PWM diagram.
Hope this help.
